Furthermore, the ultrahigh-voltage ceramic filter has the advantages of being resistant to strong currents and high voltages, sensitive in detection and durable and further has the advantages of being simple in structure, easy to manufacture, low in cost, practical, efficient and attractive.
Description
Technical field
The present invention relates to a kind of hi-line pick-up unit, particularly a kind of UHV (ultra-high voltage) ceramic filter.
Technical background
Along with the progress of life and social development, people become more and more frequent to the user demand of hi-line, and hi-line is along with increasing of access times can produce damage in various degree, these impaired hi-lines can cause greatly power loss in the process using, and continue to use these impaired hi-lines to exist very large potential safety hazard.
Nowadays people often adopt inorganic plastics to detect hi-line, and along with the continuous rising of hi-line temperature, capacity and the resistance change of plastics are very little, and the result of detection is very inaccurate.Because present stage people are also very deficient to the detection means of hi-line, just seem particularly important so design a UHV (ultra-high voltage) ceramic filter for detection of hi-line.
Chinese invention patent discloses a kind of porcelain bushing with wave filter No. CN103187946A, on the ceramics tow sides of this ceramic filter, be all designed with plated film metal level, oscillator electrode and oscillator pad, oscillator soldering pad connection line, wherein, described ceramics is rectangle, on the extexine of ceramics, be coated with plated film metal level, on ceramics, be provided with multiple lines and multiple rows shape identical and equally distributed oscillator electrode and oscillator pad, except the first row is all connected by oscillator soldering pad connection line with the every row oscillator pad the 7th row, the oscillator pad of the first row and the 7th row is not connected with every row oscillator pad of the second to the 6th row, the shape of the first row oscillator electrode and oscillator pad is contrary with the shape of other row oscillator electrodes and oscillator pad.This invention manufacturing cost higher and difficulty is larger, can not be widely used in production, very inconvenient.
Summary of the invention
The technical issues that need to address of the present invention are that the conversion by gathering ceramic temperature in ceramic filter detects the extent of damage of hi-line, thereby have reduced the waste of electric power and ensured safety; A kind of UHV (ultra-high voltage) ceramic filter is provided.
For solving above-mentioned technical matters; structure of the present invention comprises ceramic body and hollow circular tube type protective seam; described ceramic body is annular cylinder; outer surface and the inner surface of pottery body are silver coated respectively; protective seam passes the endoporus of ceramic body and is fixedly connected in ceramic body, and the interior hole dimension of the external diameter of protective seam and length and ceramic body matches.
Further again: the thickness of described ceramic body is 13 millimeters to 14 millimeters.
Further again: the outside diameter of described ceramic body is 50 millimeters.
Further again: the diameter of bore of described ceramic body is 23 millimeters to 25 millimeters.
Further again: described ceramic body and the length of protective seam are 45 millimeters to 47 millimeters.
Further again: described protective seam is hollow copper tubing.
Further again: described ceramic body be under 1300 degree high temperature, fire with 200 newton's pressure extrusion under be shaped.
Adopt after said structure, the present invention not only can detect by measuring ceramic temperature variation the extent of damage of hi-line, thereby has reduced the waste of potential safety hazard and electric power; And the present invention have resistance to forceful electric power, high pressure resistant, detect sensitive and long-lived feature; That the design also has advantages of is simple in structure, be easy to manufacture, with low cost, practicality and high efficiency and good looking appearance.

Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention.
Fig. 2 is left view of the present invention.
Fig. 3 is the temperature variant graph of a relation of the resistance value of ceramic body in Fig. 1.
In figure: 1 is ceramic body, 2 is hollow copper tubing, and 3 is silver layer
Embodiment
A kind of UHV (ultra-high voltage) ceramic filter as depicted in figs. 1 and 2; structure comprises ceramic body 1 and hollow circular tube type protective seam 2; described ceramic body 1 is annular cylinder; the outer surface of pottery body 1 and inner surface difference silver coated 3; protective seam 2 passes the endoporus of ceramic body 1 and is fixedly connected in ceramic body 1, and the interior hole dimension of the external diameter of protective seam 2 and length and ceramic body 1 matches.The thickness of described ceramic body 1 is that 13 millimeters to 14 millimeters, outside diameter are that 50 millimeters, diameter of bore are 23 millimeters to 25 millimeters.Described ceramic body 1 and the length of protective seam 2 are 45 millimeters to 47 millimeters, and described protective seam 2 is hollow copper tubing.When using, the present invention in hollow copper tubing 2, pass and make hi-line directly to contact with the inwall of hollow copper tubing 2 hi-line; The present invention measures the electric current trafficability characteristic in hi-line by detecting the temperature variation of ceramic body 1.When its electric current trafficability characteristic after the long-time use of hi-line will be lower, now the temperature of hi-line will be very high, because ceramic body 1 contacts with hi-line by hollow copper tubing 2, along with the raising of hi-line temperature, the temperature of pottery also can constantly increase, and now people, by detecting the temperature of ceramic body 1, just can determine the extent of damage of hi-line, thereby determine whether to need to change hi-line, just can better stop the waste of potential safety hazard and minimizing electric power by these design people.And the present invention silver coated 3 improves the sensitivity of ceramic induction temperature variation respectively by the outer surface at ceramic body 1 and inner surface, thereby improve the accuracy of measuring.Ceramic body 1 in the present invention contacts with hi-line by the hollow copper tubing 2 being fixedly connected with, thereby prevents the wearing and tearing of hi-line to ceramic body 1 inside surface silver layer 3, has extended the serviceable life of UHV (ultra-high voltage) ceramic filter.
Ceramic body 1 be as depicted in figs. 1 and 2 under 1300 degree high temperature, fire with 200 newton's pressure extrusion under be shaped.The ceramic body of making by high temperature and high pressure has high temperature resistant, high voltage bearing advantage, and can increase serviceable life of the present invention.
As shown in Figure 3 be the temperature variant graph of a relation of resistance value of ceramic body 1.Present stage people great majority adopt inorganic plastics to detect hi-line, the testing result of this kind of method is very inaccurate, the present invention adopts organic ceramic to replace inorganic plastics, utilize ceramic characteristic to improve the accuracy detecting, pottery is along with marked change also can occur for rising self capacity and the resistance value of temperature; In the time that temperature rise 10 is spent, resistance value declines 0.5%; In the time that temperature rise 90 is spent, resistance value declines 7% to 8%; The present invention utilizes this characteristic of pottery to detect exactly the trafficability characteristic of electric current in hi-line, thereby calculates the extent of damage of hi-line.
The present invention not only can detect by measuring ceramic temperature variation the extent of damage of hi-line in sum, thereby has reduced the waste of potential safety hazard and electric power; And the present invention have resistance to forceful electric power, high pressure resistant, detect sensitive and long-lived feature; That the design also has advantages of is simple in structure, be easy to manufacture, with low cost, practicality and high efficiency and good looking appearance.
